Title: Propeller for ship utilizing wave energy
Inventor: NISHIOKA ISHIO
IPC: F03B13/20
Filed: 1980-05-09
Abstract: PURPOSE: To effectively utilize wave energy by converting it into a propulsive force through the flex motion of a ship hull about a horizontal pin.  
     CONSTITUTION: The ship hull S is constituted from a steam body 1 and a tern body 2 which are pivotally connected with each other through a horizontal pin 3. Between the bodies 1 and 2, oil-hydraulic cylinders 4 and 5 are mounted so as to discharge pressure oil through the flex motion of the hull. Said cylinders 4 and 5 are connected with a oil-hydraulic rotator 16, to which a generator 19 is connected. Accordingly, when the rotator is rotated by the oil pressure from the cylinders 4 and 5, the generator 19 is operated, so that electrical energy is obtained. A propeller 21 is rotated by said electrical energy, providing a propulsive force.

Title: Camera with electronic finder
Inventor: YOSHIDA HIDEO
IPC: H04N5/225
Filed: 1990-03-12
Abstract: PURPOSE:To execute the finder display of an out-of-focus state at the time of photographing without varying a focal position of a lens by reducing the level of an edge part of an image signal of a non-focusing area which cannot be covered with depth of field, and executing an LCD display. CONSTITUTION:An edge detecting part 37 detects an edge part, based on an image signal from a signal processing circuit 18. When the edge part of the circuit 37 is detected, and a signal for showing a focusing state is inputted from a focusing discriminating circuit 34, an edge level variable circuit 38 generates an edge signal for emphasizing the edge part. Also, when a signal for showing a non-focusing state is inputted, an edge signal for gradating the edge part is generated and outputted to an adding circuit 20. The adding circuit 20 adds the image signal from the signal processing circuit 18 and the edge signal from the circuit 38 and displays them on an LCD 22. Therefore, an out-of- focus state at the time of photographing can be displayed without varying the focal position of a finder lens.

IPC: H04N5/783
Filed: 1994-03-31
Abstract: PURPOSE:To reproduce a natural variable speed video even if a compressed digital video signal recorded in VTR is reproduced in variable speed. CONSTITUTION:At the time of variable-speed reproduction at m-fold speed, a reproduction system decoding circuit 70 outputs data obtained by time base- expanding a compressed digital signal whose error is corrected into m-fold of a bit rate R to a data expanding circuit 75. The data expanding circuit 75 sets processing speed to m-fold, expands the compressed digital video signal and outputs the digital video signal of m-fold as much as the frame frequency Fr to a frame frequency conversion circuit 90. The frame frequency conversion circuit 90 converts the frequency into the frame frequency Fr based on a frame conversion timing signal. Since processing speed is made (m) times the processing speed, the signal is expanded and the frame frequency is converted, the natural variable-speed video can be reproduced.
